.HUB-WRENCH.

SPECIFICATION forming part of Letters Patent No. 431,641, dated July 8, 1890.

Applicatien filed May 6, 1890. Serial No. 350,757. (No model.)

To all whom it may concern:

Be it known that I, MELVILLE BEACH, a citizen of the United States, residing at Ashton, n the county of Lee and State of Illinois, have Invented a new and useful Hubrench, of which the following is a specification.

This invention has relation to hub-wrenches,

and among the objects in view are to provide an exceedingly simple and powerful wrench adapted for clamping and rigidly connecting the hub-band of a wheel with the axlenut, whereby said wheel may be removed and replaced simultaneous with the nut for the purpose of oiling, cleaning, or repairing the bear- Ing. WVith the above general objects in view the Invention consists in certain features of constructlon, hereinafter specified, and particularly pointed out in the claims. 7

In the drawings, Figure 1 is a transverse section of a hub and its axle, a wrench constructedin accordance with my invention be- Ing applied thereto and shown in side elevat1on. Flg. 2 is a perspective of the wrench in deta l. Fig. 3 is a perspective, in detail, of the b1nd 1n g member. Fig. 4is a similar view, in detail, of the opposite member.

In practicing my invention, I construct the wrench of two opposite sections or members, which are of substantially semicircular shape, and intermediate their ends are pivoted.

1 represents the binding-section, and 2 the clamping-section, and through the two is passed a pivot-bolt 3. The adjacent faces of the two sections are perfectly plain where they have contact with each other, so as to permit them to slide readily one upon the other. The inner ends of the sections are provided with transverse jaws 4, the inner sides of which are provided with recesses 5, which receive the upper edges of the opposite section, and thus serve to maintain said sections In sliding contact with each other. The outer ends of the section 1 terminate in-a perforated head 6, the perforation being threaded, and n the same is mounted a binding-screw 8, the Inner end of which projects through the opposite side of the perforation and is provided with a loose washer 9, which may or may not be provided with a felt or other covering 10. The outer end of the opposite member is provided with a laterally-disposed head 11, the opposite extremities of which are provided with threaded openings 12, arranged at an angle with relation to each other, and in the openings are mounted set-screws 13, having at their inner ends loose washers 14, covered or not by pads 15.

16 designates the hub of the Wheel; 17, the axle; 18, the nut; and .20, the hub-band. To apply the wrench, the outer ends of the members are introduced over the hub-band and the inner jaws over the axle-nut, and said members are adjusted to a proper relative position with regard to the nut and the diameter of the hub -band through the medium of the binding-screws 13. After such adjustment the screw 8 is manipulated so as to tightly bind upon the hub-band, and in so doing the outer ends of the members are laterally spread and the inner ends or jaws contracted and clamped upon the nut. It will now be apparent that both the nut and the hub are rigidly connected, and by using the wheel as a leverage and rotating to the rear the nut is removed from the axle, which latter may be cleaned, oiled, repaired, or otherwise attended to, and the wheel replaced by simply introducing the hub over the axle and giving the wheel a few turns. In this Way the wheel may be removed and replaced without separating the nut from the wheel or being obliged to lay the same down to become filled with sand and grit or soiling the clothes and hands of the operator.

Having thus described my invention, I claim 1. In a wrench, the combination, with two curved members pivoted together intermediate their ends, the inner extremities of said members being provided with nut-receiving jaws and the outer extremities of said members with threaded openings, of bindingscrews mounted in the openings, substantially as specified.

2. In a wrench, the combination, with the oppositely-curved members pivoted together intermediate their ends, theinner ends of said members terminating in laterally-disposed nut-receiving jaws, each of which is recessed at its inner edge to receive the upper edge of the opposite member, and the outer ends of which are provided with threaded openings,

of binding-screws mounted in the openings,

substantially as specified.

3. In a wrench, the combination, with opposite semicircular members pivoted together intermediate their ends and terminating at their inner ends in laterally-disposed jaws, one of said members terminating at its outer end in a threaded and perforated head and the opposite member at its corresponding end having a single-threaded perforation and the outer end of the opposite jaw terminating in a laterally-disposed head having opposite angularly-disposed threaded openings, setscrews mounted in the openings and in the single perforation, loose washers mounted on the set-screws, and pads upon the inner faces of the washer, substantially as described.

5. In a wrench, the combination of two curved members pivoted together intermediate their ends, the inner extremities of said members being provided with nut-receiving jaws and the outer extremities of said members being provided with clamping devices to engage the hub-band, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

MELVILLE BEACH.
